Default Re: How do you calculate percentage of canopy

Are you asking just out of curiosity, or do you have a specific project in mind?

I have very rarely, if ever, had a job where we had to be significantly concerned with approaching the 25% point. I think that the true moral of this story is that less is more. If you develop a solid plan with objectives before starting to prune, and develop a course of action which accomplishes your objectives with the smallest possible quantity of cuts and volume of debris, you will seldom even have to think about the "25% Question".

However, if I had to estimate the pruning limits of a specific tree, I would most likely try to divide the canopy into "zones", and not go over 25% in any one zone.

Hope this helps.
